Display or portion thereof with graphical user interface



The FIGURE is a front view of a display or portion thereof with graphical user interface showing my new design.

The broken lines showing a display or portion thereof, text and other elements form no part of the claimed design. However, the ellipsis between the claimed chevrons and horizontal lines, which is confusingly similar to the broken lines, does form part of the design. 

CLAIM The ornamental design for a display or portion thereof with graphical user interface, as shown and described.
